I may have missed it, but did you say how many chickens you will be increasing to?
From my personal experience, I built an 8x10 elevated coop, and although thatās sufficient for the maximum number of chickens we would have, I wish I would have gone bigger, even just by a little. Especially since space already turned out to be an issue for your goals of expanding! If youāre already building a bigger coop, bumping up to an 8x10 gives you options down the road... be it to expand your flock once more, or incorporate storage or brooding space. Just something I wish I would have considered!!!
Also, as far as ideas/plans, what type of environment are you in? Whatās the terrain like? Whatās the weather like? Iād love help brainstorm!
